Yes, I have a pair hanging from a string at each bookcase, two different pairs at each computer, each of which has a 20" display, since I figured out I was going blind some years ago, and others scattered about the house, to help me find the ones I really need.

I have bifocals, trifocals, but mostly single-vision glasses, since bifocals and trifocals don't allow me to read an entire line of text at once. I even have special trifocals for use at the test bench, where I have to read information on displays at eye level while probing a circuit on the bench and, at the same time, operating both a computer and signal generators, etc, which stimulate the circuit.

Even so, the spectacles don't help with the chosen (not by me!)colors, which make text hard to read.
